Many impacts of Global Environmental Assessment (GEA) processes on policy processes, and the mechanisms underlying these impacts, remain underappreciated. In this research, we focus on the 5th Global Environment Outlook and the Working Group III contribution to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. Based on the perception of GEA process participants, we describe the mechanisms through which assessments create or alter interpersonal interactions which can affect the dissemination of ideas. In particular, we find that GEAs can contribute to framing international coordinative discourses in intergovernmental negotiations. This can be achieved by widening, improving and/or maintaining the active participation of policy actors in the discussions of global environmental risks and by creating the scientific foundations for intergovernmental negotiations. GEAs can also contribute to national coordinative discourses by facilitating reflexive learning amongst participants, empowering them to diffuse and translate global information, and by providing methodological guidance. They can contribute to national communicative discourses by reviving interest and awareness of the urgency to address environmental problems. In this way they provide powerful arguments for governmental societal actors to challenge or strengthen existing national coordinative discourses. Finally, GEAs can improve scientific discourses worldwide by enhancing the capacity of individual researchers to produce and communicate relevant research insights. This is achieved by participating in a learning exercise with an extended community of peers and policy actors. This article is part of a special issue on solution-oriented global environmental assessments.
